Hi Guys, I have just designed and built an infra red remote volume control for my hi fi system. The question is how to mount the sensor on the faceplate which is wood, so that it looks professional i.e some type of lens? Any ideas?

Hi,

Is it in a T1 or T1-3/4 case, or one of those right-angle dealies?

If in a regular LED case, it's fairly easy.

Cheers!

Then the likely way to proceed is drill (with a forstner bit) a 3/8" hole and glue on the inside an IR window. Steal an IR window from a cheap remote from the thrift store.

:2c:

Cheers!

Hi, I usually drill a cut out with a router (any similar tool will work) and then use one of the small snap in lenses for LEDs. I believe Jameco has them in stock. I seem to recall getting 100 for about $10. Then I hot melt glue the sensor in place. If you expect to have to remove it ever then use blue tack on it instead.

Good listening
Bruce

Snap lenses for right angle devices? Got a link, I need some!

Hi, They are like this part number 143132 from Jameco. What I do is make a space in the wood deep enough for the sensor and drill a hole to it from the front. Then press the lens into the hole. The lens is a sort of Fresnel one and works well with opto sensors. If the wood isn't thick enough you can cut off part of the sleeve on the lens. I see they have raised the price since I got them last (what else is new) to $.19 each in sets of 10 and $.17 each in 100's.

Good listening
Bruce

I found some of these marbles that are used in mosaics, they are flat at the bottom and I will drill a recess with a flat blade drill bit and after drilling a 4 mm hole through the wood face, glue them in.
